The mouse also generates its own clock signal. Wait at least microseconds 3. Release Data Clock high and Data high will put the mouse into idle mode and if Data Reporting has been enabled, the mouse should send a Data and Clock signal to the PIC when it detects button changes or motion Optical mice with wheels and additional buttons generally send a fourth data packet, but for this lab, that data was not needed. Each high and each low on the clock signal would last roughly 40 microseconds and our interrupt service routine which was supposed to trigger every time the clock went from high to low tended to miss or skip several signals at a time.

The clock and data lines connect directly to the clock and data lines of the breadboard adapter. Interpret the X and Y motion bytes Content may change as the project progresses.
Qtronix iOne Lynx M9 3-Button Optical Mouse – Black
Documentation and ordering information for the adapter can be found here: We also found that the buffers were lnyx. More about this can be found muose the PS2 protocol section. This article documents an unfinished work. Wait at least microseconds 3. Wait for clock to go low Release Data Clock high and Data high will put the mouse into idle mode and if Data Reporting has been enabled, the mouse should send a Data and Clock signal to the PIC when it detects button changes or motion Set Clock low 2.
Setting Data low and Clock high is the host requesting to send command, and this should cause the mouse to start generating clock signals and to wait for commands from the host 5.
Interpret the direction bits explained in the Mouse Interface section Views Page Discussion View source History.
Ione Lynx M9 – mouse Series
The mouse also generates its own clock signal. Set Data low 4. Interfacing with a mouse From Mech. R is for the right button and L is for the left button where 1 equals pressed and 0 equal unpressed.

So if the PIC wants to send data to the mouse, data will equal output D inverted, and Clock will equal output C inverted. Mokse order to operate, the mouse needs power, so the 5v and ground are used to power the mouse.
Our code shown further down attempts to display X and Y coordinate motion of an optical mouse by doing the following: A great way to trouble shoot, debug, and see the final result is to use an LCD screen to mouze the information that the mouse is sending to the PIC.
moue The code, circuit diagram, and notes about the interface are included. Personal tools Log in. When the clock is set low, the host will wait us before reading the data stream. The mouse’s XY coordinates will be displayed on an LCD screen and will be updated when the mouse moves.
This data transmission takes place based on the clock signal generated by the external device. The other two pins are actually used as both inputs and outputs.
More information about LCDs and the flex code we used can be found here: A start bit, eight data bits, a parity bit oddan end bit, and in the case of host-to-device transmission, an acknowledge bit. This is a visual representation of a byte of information being sent from the mouse to the host:. More information about this operation can be found here: More information on the mouse interface may be found at the following links: Each high and each low on the clock signal would last roughly 40 microseconds and our interrupt service routine which was supposed to trigger every time the clock went from high to low tended to miss or skip several signals at a time.
Optical mice with wheels and additional mm9 generally send a fourth data packet, but for this lab, that data was not needed.
